Decks are popular on walkout basements and second floors around the metro. Footings have to go below the local frost line, and strong UV breaks down wood finishes quickly. That's why composite decking is so common here.
What decks typically costs in Denver
| Scope | Typical range (estimate) | What that usually covers |
|---|---|---|
| Pressure-treated (320 sq ft) | $11,500 – $20,000 | wood decking and rail |

Decks: common questions
Composite or wood in Denver?
